What is Density Fiberboard?

MDF furniture

Density Fiberboard is an engineered wood product made from wood fibers or other plant fibers. These fibers are processed, combined with synthetic resin, and then pressed under heat and pressure to form the board. Due to its uniform structure, fine texture, stable performance, impact resistance, and ease of processing, Density Fiberboard is widely used in furniture, interior decoration, musical instruments, and packaging.

Density board is classified into three types:

  1. Medium Density Fiberboard (MDF): With a density ranging from 0.65g/cm³ to 0.80g/cm³.
  2. High Density Fiberboard (HDF): With a density greater than 0.80g/cm³.
  3. Low Density Fiberboard (LDF): With a density ranging from 0.45g/cm³ to 0.65g/cm³.

These classifications are based on the density of the board, which affects its properties and suitable applications.

Uses of Density Fiberboard:

  1. Mainly used for laminated wood flooring, door panels, partitions, and furniture.
  2. In home decoration, MDF is primarily used for surface treatments in mixed-oil processes.
  3. Medium density fiberboard (MDF) is generally used for making furniture because high density fiberboard (HDF) is too dense and prone to cracking, making it unsuitable for furniture.
  4. High Density Fiberboard (HDF): Typically used for interior and exterior decoration, office and household furniture, acoustic equipment, vehicle interiors, anti-static flooring for computer rooms, wall panels, security doors, partitions, and other construction materials. It is also a good packaging material. In recent years, it has been used as a base material for making laminate flooring.

MDF is especially widely used in furniture manufacturing. For cutting MDF, especially laminate MDF boards, recommended

Advantages of MDF:

  1. Uniformity: Due to the thorough mixing and even distribution of fibers during production, density board has a highly uniform internal structure.
  2. Smooth Surface: The surface of MDF is very smooth, making it ideal for painting, veneering, and other surface treatments. Various materials like wood veneer, printed paper, PVC, adhesive film, melamine-impregnated paper, and thin sheets of light metal can be applied to the surface of MDF.
  3. Good Machining Performance: MDF is easy to cut, mill, and drill, making it suitable for manufacturing various furniture and decorative items.
  4. High Strength: Compared to particle board, MDF has better bending strength and impact resistance.
  5. Moderate Weight: MDF has a moderate weight, making it neither too heavy nor too light, which facilitates handling and installation.
  6. Cost-Effective: Due to the efficiency of the production process, MDF typically offers high cost-effectiveness.

These characteristics make MDF a versatile and popular choice in the furniture and construction industries.

Disadvantages of MDF:

  1. Lack of Moisture Resistance: The biggest drawback of MDF is its lack of moisture resistance. It swells when exposed to water. When using MDF for skirting boards, door frames, and window sills, it’s important to paint all six sides to prevent deformation.
  2. High Water Expansion Rate: Although MDF has poor moisture resistance, it boasts a smooth and flat surface, fine texture, stable performance, firm edges, and is easy to shape. This helps avoid issues like decay and insect damage. Additionally, MDF has better bending and impact strength compared to particle board and offers excellent surface decorativeness, often surpassing the appearance of solid wood furniture.
  3. Poor Screw Holding Capacity: MDF has a poor screw holding capacity due to its fine fibers, which makes it significantly less effective than solid wood and particle board in this regard.

These disadvantages highlight the limitations of MDF, particularly in environments where moisture is a concern or where strong screw holding is required.

Although MDF has poor moisture resistance and screw holding capacity, making it difficult to re-secure screws if they loosen, it has several advantages. MDF has a smooth and flat surface, fine texture, stable performance, firm edges, and is easy to shape. These characteristics help prevent issues such as decay and insect damage. Additionally, MDF surpasses particle board in bending and impact strength, and its surface is highly decorative, often exceeding the appearance of solid wood furniture.
